My 928 has ABS so it is a chore to get the setup just right for max braking. A combination of rear bias, tire grips and rear damper rebound. Too much rear bias and the rears lock and kick on ABS too soon. Too little rear bias and the front locks and kick on ABS too soon. Too soft rear rebound and the rears lock too soon, to firm and the car doesn't rotate on turn-in. Change tires and/or tire pressures and the whole setup is off.

I would love an adjustable rear bias valve. But haven't found a suitable replacement for the stock Porsche parts which require swapping the valve to change bias.
